Patent EP-0374382-A1 (EP)
Inventor: SCHMIDT BERNHARD
IPC: F02K9/64
Filed: 1989-09-22
Abstract: A method of cooling walls, to which hot gas is applied, of flow channels in air-breathing hypersonic engines, operated partially or exclusively with hydrogen, in particular of air guidance channels, nozzles and ram-jet combustion chambers in combined engines for space shuttles and hypersonic passenger and transport aircraft. The hydrogen mass flow is led entirely or for the most part through the wall structures of the flow channels and subsequently burned in at least one of the combustion chambers of the hypersonic engines in order to generate thrust. The wall structure consists on the hot gas side of thin walled, mutually connected tubes (4), which abutt one another and have constant cross-sections over the length of their respective cooling regions, and consists on the side averted from the hot gas of one part or multipart support element (6) which is essentially mechanically loaded. <IMAGE>

Abstract: Coolyimides and copolyamide-acids having improved solubility and processing characteristics are provided having incorporated into the polymeric chain as a novel aromatic diamine compound, 2-(3-aminophenyl)-2-­(4-aminophenyl) hexafluoropropane (3,4′-6F Diamine). The copolyamide-acids and copolyimides are prepared by reacting the 3,4′-6F Diamine with a mixture of two or more aromatic tetracarboxylic acids or anhydrides thereof. It has been found that the copolyimides of this invention have improved solubility characteristics, low dielectric constants and improved thermal flow properties as a consequence of the meta/para positioning of the amino groups on the diamine, which renders these copolymers more readily melt spinnable for the production of fibers. The copolymers may also be compression molded and fabricated into composites at moderate temperatures and pressures. Solutions of the copolyimides may be cast into films.

Abstract: A strap (100) comprised of a layer of magnetic material (108) on a layer of nonmagnetic conductive metal (106) comprises a self-regulating heater, which is wrapped around a length of heat recoverable tubing disposed around a terminal being terminated to a conductor wire (70), or a pair of wires being spliced. When energized, the strap (100) generates thermal energy melting solder of a preform within the tubing, terminating the terminal to the wire (70), or the two wires together, and sealing the termination simultaneously. A plurality of terminals in a connector housing (40) include solder tails extending rearwardly from the housing (40) so that respective wire ends may be placed therealong within solder preforms within heat recoverable tubing therearound. A strap (100) comprising a self-regulating temperature source is wrapped around the array of solder tails and wire ends (76) and is energized to solder the array and seal the terminations. A high frequency alternating current induced in or transmitted to the magnetic layer (108) of the strap (100) causes the strap to generate thermal energy sufficient to melt the solder and shrink the tubing. The strap (100) may have several layers and may be shapable to conform to the outer surfaces of the heat recoverable tubing lengths. A strap may seal an open end of a length of heat recoverable tubing having a sealant preform therewithin, when wrapped therearound and energized.

Abstract: A display system having a display memory, a palette and a digital-to-analogue converter stage is able to support both an indirect colour mode and a direct colour mode. In the indirect colour mode, pixel data from the display memory is used to access chrominance and/or luminance data from the palette for conversion in the converter stage into analogue values for controlling a display device. In the direct colour mode, pixel data in the display memory directly specifies the chrominance and/or luminance data for conversion in the converter stage into analogue values for controlling the display device. In the direct colour mode, however, the converter stage is also responsive to data from the palette for producing the analogue values for controlling the display device. The invention permits the provision of direct as well as indirect colour modes in a flexible and efficient manner, with the provision of a plurality of formats for the direct colour modes being achieved by loading appropriate information into the palette.

Title: Dimensional measuring chain with a linear output
Inventor: BRUERE ALAIN
IPC: G01D5/22
Filed: 1989-12-11
Abstract: The capacitive dimensional measuring chain with linear output consists mainly of a capacitive sensor (1a) formed by a detection electrode and a guard electrode surrounding the detection electrode supplied respectively by two sources of bias voltage (Vp, V'p), a reference capacitor (6a) supplied by a reference voltage source (7a), and a circuit (9) which measures the distance (e) between the detection electrode and a conducting component (P) placed opposite this electrode. The sources of bias voltage are variable and are controlled in amplitude by a distance-measuring signal (Ve) delivered by the measuring circuit. The measuring circuit contains means (90 to 93) for amplifying and demodulating an input error signal which represents a difference between a charge on the capacitance of the sensor (Ccpt) formed between the detection electrode (10) and the component (P) separated by the distance (e) to be measured and a charge on the reference capacitor. The distance-measuring signal supplied by the measuring circuit represents linearly the distance to be measured (e) and, because of the control of the amplitude, stabilises the sources of bias voltage in temperature and time.

Abstract: La présente invention se fonde sur la découverte que des polymères ordonnés, tels que le PBzT, peuvent être aisément façonnés en structures tubulaires qui gardent l'orientation biaxiale qui leur a été conférée pendant le traitement, et que ces composants tubulaires très rigides peuvent présenter un coefficient de dilatation thermique (CTE) proche de zéro. Ces matériaux ne sont pas affectés négativement par d'importantes excursions thermiques, par exemple le passage d'une forte chaleur à un froid intense en un court laps de temps, ni par une longue exposition à l'une ou l'autre de ces températures extrêmes. Les composants tubulaires ci-décrits représentent ainsi un perfectionnement révolutionnaire des matériaux destinés à l'utilisation dans l'espace, étant donné que les températures extrêmes qui y règnent n'affectent pas la rigidité des structures bâties avec lesdits composants.
